CS Instruments

CS Instruments GmbH & Co. KG with locations in 24955 Harrislee and 78052 Villingen-Schwenningen/ Tannheim, is managed by Dipl. Eng. (FH) Wolfgang Blessing as sole Managing Director.

CS Instruments GmbH was established in the year 2002 by Christian Schuldt and Wolfgang Blessing as equal shareholders/Managing Directors.

Wolfgang Blessing already was sound a specialist on the sector of compressed air technology resp. industrial measurement technology long before the establishment of CS Instruments GmbH in the year 2002. Prior to the foundation of CS Instruments GmbH Dipl. Ing. (FH) Wolfgang Blessing acted for more than 10 years as primarily responsible product manager for industrial measurement technology at a worldwide known manufacturer of measuring instruments for compressed air and gases in the Black Forest. The technical knowledge and experience matched with the long-term practical knowledge was the corner stone for the success of CS Instruments.

Features

  • Measurement of mass flow rate, output of standard volume flow rate
  • High accuracy for both small and large flows
  • Pressure and temperature compensated by the thermal mass flow principle
  • Easy installation and removal of the sensor, the integrated measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
  • No moving parts, therefore low maintenance
  • Vanishingly low pressure loss due to vanishingly low blockage of the diameter
  • Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.

Applications

  • Application report underwater noise protection
  • For oxidizing gases
  • for noble or rare gases
  • for argon, nitrogen and helium in aerospace engineering
  • for argon, helium and nitrogen in the automotive industry
  • for argon and nitrogen in metal production and metal processing
  • for nitrogen generators
  • for welding gas
  • for the food and beverage industry
